Hi Bill,

this is not a problem of the compiler. All these functions need a file operating system.
But typically no file oriented data storage device attached to an 8051.
So why should Keil implement useless functions ?


There are some 8051 derivates, which understand Intel-Hex directly and can write it into its own program memory, e.g. Dallas DS5000 (32kB nonvolatile SRAM), Atmel T89C51RD2 (64kB Flash)
